SHEET-METAL BOX.

Application filed January 21, 1907. Serial No. 863,177.

cityof Chicago, in the county of Cook and .State -of Illinois,have'invented a new and useful Im rovement in SheetMetal Boxes, 01 whicht e following is a specification.

My Invention relates to boxes or cans formed frofn thin sheets of metal,and provlded with covers of like material, which V may be removed orreplaced indefinitely as ortions of the contents are required for use.

he bod portions of such cans are usually rovide with a bead orridgepressed out rom the inside at a short distance from ,the per edge, andwhich forms a stop upon ich the edge of the cover may rest. The cancover is commonly made from one piece, stamped with others from'a flatsheet of metal, and then formed indies oi the desired shape and. size.When properly made the cover fits snugly about the upper portion or rimof the can, and the edge rests upon the bead, but when so constructedthe cover is removed with difficulty and replaced with inconvenience.This condition is ag ravated if adhesive materials are inclose in thebox and get between the' adjacent surfaces. In any event the cover mustbe removed by cuttingaroufid under the edge of the cover or by drivingit ofi with a hammer or similar instrument. The parts of the boxbecomethus more or less distorted, the cover -is hard to' replace, andthe eificiencyof the box for preserving its contents is impaired. Byconstructing such boxes, however, according to the principles of myinvention, the cover may at all times be leadily'removed. Leverage maybe ap lied asnecessary to overcome 'a too ti ht lit or adhesion frominclosed material. ft is not injured or so distorted. as to cause thecontents to be exposed, while, owing to its conformation, thecover maybe readily replaced after removal.

In the drawings? Figure l is a perspective .view of a box having thecover portion removed; Fig. 2 is a top View of the cover; 3 is a partialvertical section of the box, and Fig. 4 is a key by which the cover maybe removed. k

Further describing my invention with reference to the drawings; A is thelower or. body portion of a box, which is provided near its u or portionwith the peripheral bead E. e latter may be of the usual form, but

original form of the cover blanks.

the manner I prefer to construct it with the upper part somewhatflattened, as shown at C. The upper part of the box body, above thebead, forms a rim D with substantially vertical sides. About this thecover F fits snugly so that the edge of the latter F rests upon the headthroughout its greater portion, but for a small part o'i-itscircumference the edge of the cover is extended outwardly to form thelip G. This I prefer to provide for in the Nhen these are cut from metalsheets there is a considerable amount of waste between the externalcurves of the cover blanks. By having the dies appropriately shaped thecover blank is given a small projection which is formed from suchinterstitial portion and this, whenacted upon by the forming dies,provides the lip G at practically no additional cost for material orlabor. The said lip should be turned upwardly and outwardly on the curveH, so as toleave a slight space I between the lower edge of the lip andthe upper edge 0 of the bead. Into this space or slot the edge K of thekey, shown in F 1g. 4, or any other thin piece of metal, as the backof'a knife blade, may be inserted, when a slight twisting motion willrelease the contact of the cover and suflice to remove it. When the sameis to be replaced, by placing the edge furthest from the lip in positionon the can rim and resting on the head, the

slanted inside of the top under the lip will act as a guide, and aslight pressure on the lid at the oint L will restore the cover to itsclosed position. if preferred, the ii p G may also be formed from aerfectlyround disk, by turning the edge 0 the cover up for a slightdistance. in this case a slot will be formed between the lip and thehead, but the lip will not roject as far aswlwn made in rst abovedescribed.

I claim and desire to secure by Letters Patent the following:

1. A box comprising a body portion having an annular bead struck outv lierrfrom below the upper edge of the body, combined with a cover havinga rim to (it over and inclose that portion of the body above the headwith its lower edge resting on the upper face of the head, the saidcover rim having a part thereof extended outwardly to form a lip, thesaid ortion forming the lip being curved outward y and downwardly, andthou outwardly, whereby the free edge of the lip lies above'and freefrom contact with tho upper 1' outwardly and downwardly, and thou outlip forming a space belwmn the lip and the Wardly, whereby the. frooodgoof tho lip lies adjacent port-ion oi Lhe box body and the avboveandfroofromoonmcluwil h tlielhitla-ov mlrved underneath face of tho lip actingas a of the hood, the out ordcurving of the li guide when placing; thevowi' in position. 3 forming; ii space between the lip and tho & 2.
